From the examples above, we can conclude that all roots  are  bases  but  not  all  bases  are  roots. Bases are called stems only in the context of inflectional morphology Katamba, 199:45
3. Morpheme
A morpheme is the essential unit in word construction,  the  smallest  meaningful  component  of language  which  conveys  message  containing  meaning  or  function  O’Grady  and   Guzman,
1996:133. While according to Allan 2001: 108, a morpheme is the  smallest  unit  of  syntactic analysis with semantic specification. A word may consist of one  or  more  morpheme  like  what
Langackers says that morpheme is the minimal units of grammatical structure, such  as  the  four componants of unfaithfulness 1973:75.
A mopheme as the smallest unit of language  can  not  be  separated  into  smaller  part  again. Morpheme is used to refer to  the  smallest  invisible  unit  of  semantic  content  of  grammatical
which word is made up of, for examples : The word “friends”  consist of two morphemes: friend and –s which indicates plural form
The word  “beautiful”  consist of two morphemes: beauty  and  –ful  which  indicates  adjective form
The word “cooks”  consist of two morpohemes: cook and  –s  which  indicates  simple  present tense that the subject is singular
Morpheme can be classified into bound morpheme and free  morpheme.
A  morpheme  that can be a word by itself is called free while a morpheme that must be attached to another  element
is said bound morpheme O’Grady and Guzman, 1996: 134. In other word, they must be  joined to other  morphemes  as  parts  of  words  and  never  stand  alone  by  themselves,  for  instance:
prefixes, infixes, and suffixes. On the  contrary,  free  morphemes  are  those  that  can  stand  by themselves as free units, to put it more simply, they need not  be  attached  to  other  morphemes.
Here are some examples of bound and free morphemes :
|Free morpheme|Local-  |-able   |certain    |Require     |Order   | |Bound        |-ly     |Dis-    |Un-        |-ment       |-ly     |
|morpheme     |        |        |           |            |        | |Words        |Locally |disable |Uncertain  |requirement |Orderly |
4. Lexeme and Word
Lexemes and words are linguistic units bigger  than  morphemes.  Lexemes  and  words  are  two different terms. In general, we can say that lexemes are vocabulary items listed in the dictionary.
Lexeme                                            Words Study                                    Studying, studies, studied
Cook                                     cooked, cooking, cooks O’Grady and Guzman 1997: 132 explained, “Of all units of linguistic  analysis,  the  word
is the most familiar. The most reliable defining property of words is that  they  are  smallest  free forms found in language”. Many linguits agree that word is a linguistic  form  which  may,  at  the
same time, also be a morpheme like bed; table, go,  John,  will,  to;  but  they  also  be  linguistic form larger than one morpheme like boyish, walked, books, slowly.
The ‘word’ can also be seen as a presentation of a  lexeme  that  is  associated  with  certain morpho-syntactic  properties  such  as  noun,  adjective,  verb,  adverb,   pronoun,   proposition,
conjunction and partly syntactic properties such as tense aspect,  mood,  gender,  number,  etc. Katamba, 1993:19
5. Word Formation Process
According to the Dictionary of applied Linguistics, word formation is the creation of a new word Richard et. All, 1990:321. In  this  research,  the  writer  uses  the  theories  of  word  formation
combined from O’Grady and Guzman 1996, Katamba 1993, Allan 1986, Hatch and  Brown 1995, and Kridalaksana 2007 to analyze the data. Here are the word formation processes:
1. Compounding
According to O’Grady and Guzman 1996:143, one type of  morphological  process in language is termed compounding. It is defined as combination of some lexical  categories
such as adjectives, nouns, verbs, or prepositions in purpose of constructing  a  larger  unit  of word. The same idea also is stated by Allan 1986:225, compounds are  lexemes  composed
from two or more free forms, for examples:
facebook derived from Noun + Noun anticlimax derived from Adjective + Noun
Come-on derived from verb + preposition Swear word derived from verb + noun   Allan,1986:225
O’Grady and Guzman 1996:154-155 also divide types of compound into two:
a. Endocentric, compound that identifies the general class which  the  meaning  of  the entire word belongs. In most cases
e.g : dog food is a
type of food a cave man is a type of man
b. Exocentric, the meaning of compound does not follow from the me
aning of  its  parts in this way In a smaller number of cases.
e.g :
- greenbottle is not a type of bottle; rather, it is a fly of the genus lucilia - redneck is not
a type of neck but an ultra consevative, white working-class person
In conclusion, a compound word at least consist
s of two bases, both are words,  and  at  any rate, root morphemes Katamba, 1993:54.
